Title: Hydroponic system
Inventor: PEDERSEN LEIF
IPC: A01G31/02
Filed: 1982-01-27
Abstract: In order to be able to utilize a hydroponic system in the best possible way and at the same time to secure the best possible growing conditions for the plants, including especially the supply of oxygen to the roots in the simplest possible way, the system is built up by means of a plurality of fluid containers (1) with an overflow (2 or 17) and with an upper section (3). In this upper section (3) a nutrient substrate (4) e.g. consisting of foam can be mounted e.g. in a way to permit the formation of an air space (5) between the substrate (4) and the fluid (15). The fluid is led to the container by means of a tube (6) ending at the bottom. This secures the supply of nutrient and oxygen to the roots. To secure the outlet from the container a tube (8 or 9) is arranged that is supplied with apertures (10) at the top at an equal distance to each other. Accordingly, arches (7) with projections (11) are provided in the bottom, so that the container can be 'locked' firmly to the tubes. One of the tubes (8, or 9) may further act as a drain for the fluid, which can drip from the container down into the apertures (10) of the tube, either through an external overflow (2) or through an internal overflow (16), ending in a tube stub (17) at the bottom of the container.

Title: Downhole liquid-well pump
Inventor: OWEN DOUGLAS B
IPC: F04B43/113
Filed: 1983-09-28
Abstract: Pump modules (30) and transfer modules (32) have vertical elongate housings (34) with end couplings (36, 38) and internal gas and liquid passages extending therethrough from upper coupling cores to lower coupling cores. Each pump module also has a bladder (44) extending between the end couplings around the internal passages with the couplings having passages connecting one of the internal passages to a space on one side of the bladder. When a pressurized gas is supplied through the coupling passages, the bladder forces liquid therein upwardly into the next module. At the same time, gas is exhausted through the coupling passages of the next pump module, so enabling it to receive liquid from the pump module therebelow. The transfer modules conduct the liquid up from each pump module to the next and connect the gas passages so as to enable the gas to operate the bladders. The pump may be employed in an oil well. <IMAGE>

Title: Coin discriminating apparatus
Inventor: CHAPMAN COLIN KENNETH LEONARD
IPC: G07D5/08
Filed: 1984-02-08
Abstract: Various electrical coin testing arrangements are described which may be used in coin sorters or in coin validators for example. In each arrangement a transmit coil is pulsed with a rectangular voltage pulse and the eddy currents in an adjacent coin under test are monitored, either by monitoring the resulting current in the same coil or in a different coil. In one arrangement particularly suitable for a coin validator, a single coil (3) acts as both a transmitter and receiver and is successively pulsed with voltage pulses of different lengths, and the decaying eddy currents are measured by measuring the coil voltage after delays which are longer for longer voltage pulses, in order to reduce the the dynamic range requirements of the monitoring circuitry (A, M). In a second arrangement, Figure 4, two transmit coils (3, 4) are used, the larger coil (3) being larger than each of the coins (6) to be tested, and the smaller coil (4) being smaller than each coin. <IMAGE>

Title: Bale handling device
Inventor: WILLIAMS JOHN BEALE
IPC: A01D87/00
Filed: 1986-06-21
Abstract: A bale handling device to facilitate bale-wrapping comprises a raisable rigid frame 10 adapted to be secured to a tractor three-point linkage and a bale engaging means 28, 30 rotatable on a shaft 12 which is displaceable with respect to the frame 10 and which is adapted to be moved, on raising of the bale from the ground on raising the frame by the weight of a bale engaged thereon, into frictional driving engagement with a driving shaft 44 adapted to be driven by the power take-off of the tractor. The bale engaging means, comprising a rubber wheel 32 adapted to be driven frictionally by the driving shaft 44, is carried on an arm 16 pivotally mounted on the frame 10 and biassed upwardly by spring 34 to urge the rubber wheel 32 into frictional engagement with a lug 36 on the frame. When the device is inserted into a bale and the frame lifted upwardly, the weight of the bale causes the arm 16 to pivot downwardly bringing the rubber wheel 32 into frictional engagement with the driving shaft 44, causing the bale to be rotated. When the bale has been rotated sufficiently for it to be wrapped, the frame is lowered, bringing the bale into contact with the ground. This causes the rubber wheel 32 to disengage the driving shaft 44 and to abut the lug 36 thereby stopping the rotation of the bale almost immediately. <IMAGE>
